Visual examples of unfounded warranty

Must be checked: If the teeth of starter drive (Pinion) have the abrasion symptoms.

Causes: Starter motor with the engine of the vehicle already functioning or error of use.

Must be checked: To check the motor and vehicle voltage applied. If the motor is 12V and the vehicle is 24V, the application is incorrect.

Causes: error of application.

*It is only possible to check with the starter motor removed.

Must be checked: Drop marks and hits.

Causes: adaptation of the starter motor in vehicle, installation error or accidents.

Must be checked: If all the securing holes have pressure marks in the circular region. If they do not have similar marks on all holes, it indicates that the Motor has not been fixed correctly.

causes: Installation error.

Causes: Product violated, maintenance attempted or unauthorized repairs.

Must be checked: if one or more parts of the starter has different aspects from the others, for example: broken seals or seals of different colors.

Causes: Product violated, maintenance attempted or unauthorized repairs.

Must be checked: Integrity of cables and electrical harnesses, looking for evidences of modification on original product.

Causes: Modification of the original electrical circuit of the product and/or vehicle, violation of the product, attempted maintenance or unauthorized repairs.

Must be chacked: if the Start relay has a different appearance from other parts of the starter motor or if it is not of the ZM. If there was removal of the seals and there are different colors of sealing.

Causes: Product violated, maintenance attempted or unauthorized repairs.

Must be chacked: if the product is actually of the ZM brand, through the identification tag, ZM brand on the Starter Relay and / or fastening screws/bolts.

Must be checked: If there is a large amount of oil covering all or part of the starter motor.

Causes: Oil leakage in the engine of the vehicle because the oil has the property of acting as an electrical insulation, causing failures or, even, preventing the starter motor from working.

Must be checked: If there is liquid inside the starter motor (sometimes turning the starter motor from side to side, it is possible to observe the water flow even in small quantities). If the starter motor is completely covered by mud or with severe oxidation on the surface.

Causes: use of the vehicle in flooded areas, washing the engine of the vehicle without due protection of the starter motor.

Must be checked: the smell of burnt, which may be present and yet the starter motor still running. This indicates that the starter motor has reached high rotations in free run speed.

Causes: bench test reaching high rotations.

Must be checked: If the date of installation of the starter motor is, a maximum of 180 days before the current date. If there is the tax coupon or sales note to the consumer. If the certificate is correct and fully completed.

Qué verificar: caso los cables de la bobina de retención del Relé de Arranque (bobina externa) presentan oscuros, con fragmentos sueltos del barniz y fuerte olor de quemado.

Causas: insistencia en el arranque.

*Solo se puede verificar con el Relé de Arranque desmontado.

Qué verificar: en el caso del cable (aparejo) que conecta el Relé de Arranque al Motor se presenta oscuro y con aspecto de quemado.

Causas: insistencia en el arranque.

Must be checked: Alterations marks in holes, grinding marks, oblong hole (elliptical, oval).

Causes: Alternator adaptation in non-compatible vehicle, installation error.

Must be checked: Make sure if there are beats and/or drops marks.

Causes: Alternator adaptation in non-compatible vehicle, installation error, accidents.

What to check: Alternator adaptation in non-compatible vehicle, installation error.

Must be checked: If one or more parts of the Alternator present different aspects from the others. Also check if there are cracked/broken seals or different colors of seals.

Causes: Product violated, maintenance attempted or unauthorized repairs.

Must be checked: Large amount of oil covering all or most parts of the Alternator. Furthermore, to check if the connections and threads of the connections are not wrinkled or damaged.

Causes: Error in mounting the connections of the Vacuum Pump.

Must be checked: if the regulator has different aspect from the others. Check also if there are broken seals or different colors of seals.

Causes: Product violated, maintenance attempted or unauthorized repairs.

Must be checked: if the product is actually from ZM brand through the identification label and / or fastening screws.

Must be checked: the presence of liquid inside the Alternator (sometimes turning the Alternator from side to side, it is possible to observe the water coming out, even in small quantity). Observe if the Alternator is completely covered by mud or with severe oxidation on the surface.

Causes: use of the vehicle in flooded areas, washing the vehicle motor without the proper protection of the Alternator.

Must be checked: : If there is a large amount of oil covering all or parts of the Alternator. On alternators with Vacuum Pump lubricated with Engine Oil from the vehicle check that the connections and threads connections are not crumpled or damaged.

Causes: Oil leakage in the vehicle engine, because the oil has the function property as an electrical insulation, causing failures or even preclude the operation of the Alternator. Connection error of the vacuum pump connections.

What to check: If the date of Alternator installation is in a maximum of 180 days before the current date. If there is the tax coupon or sales note to the consumer. If the certificate is correct and fully completed.
